Coinbase Developer Platform supports webhook subscriptions across several products, all using the same underlying API and authentication. Use webhooks to receive real-time HTTP notifications when events happen onchain, in your wallets, or across your CDP accounts.

​
Getting started

Before you get started, ensure you have:
Sign up at portal.cdp.coinbase.com, then navigate to API Keys and select Create API key under the Secret API Keys tab.
  1. Enter an API key nickname (restrictions are optional)
  2. Click Create
  3. Secure your API Key ID and Secret in a safe location
You’ll need an HTTPS URL to receive webhook events. For quick testing, webhook.site gives free temporary URLs instantly.For production, use your own HTTPS endpoint.
Install cdpcurl to make authenticated requests to CDP APIs:
# With Homebrew
brew tap coinbase/cdpcurl && brew install cdpcurl

# Or with Go
go install github.com/coinbase/cdpcurl@latest
